I remember when you could go to Twitter.com and see the global firehose on the front page. They had no traffic. The global feed was mostly employees and their friends talking to each other.

When Twitter started to get traction, a year or two into their existence, I decided that Twitter was the Best Thing Ever. I realized that Twitter, because of their API, actually was a real-time protocol to connect various services in a novel way. I had debates with my other tech-nerd friends about whether Twitter could be one of the fundamental building blocks of the Internet via their powerful API. When reporters or investors asked me what I thought the most exciting company in the valley was, I would invariably answer “Twitter”.

As I understand, a hugely divisive internal debate occurred among Twitter employees around this time. One camp wanted to build the entire business around their realtime API. In this scenario, Twitter would have turned into something like a realtime cloud API company. The other camp looked at Google’s advertising model for inspiration, and decided that building their own version of AdWords would be the right way to go.

As you likely already know, the advertising group won that battle, and many of the open API people left the company. While I can understand why the latter camp wanted to build an ad-based business, the futurist in me thinks this was a tragic mistake. If you are building an advertising/media business, it would then follow that you need to own all of the screen real-estate that users see. The next logical step would be to kill all 3rd-party clients, and lock down the data in the global firehose in order to control the “content”.

Perhaps you think that Twitter today is a really cool and powerful company. Well, it is. But that doesn’t mean that it couldn’t have been much, much more. I believe an API-centric Twitter could have enabled an ecosystem far more powerful than what Facebook is today. Perhaps you think that the API-centric model would have never worked, and that if the ad guys wouldn’t have won, Twitter would not be alive today. Maybe. But is the service we think of as Twitter today really the Twitter from a few years ago living up to its full potential? Did all of the man-hours of brilliant engineers, product people and designers, and hundreds of millions of VC dollars really turn into, well, this?

Nowadays, every time I get a K-Mart ad in my feed, or see wonky behavior in the official clients, or see Twitter drop another bomb on their developer ecosystem, I think back and wish the pro-API guys won that internal battle.

UPDATE: Based on the widespread support of the points made in this post, I have announced a proposal here.
